PRIMING CUP.-

Application filed December 29, 1919.

To all whom it may concern:

Be it known that I, J OSEPH C. CoULoMBn, a citizen of the United States, residing at Kokomo, in the county of Howard and State of Indiana, have invented certain new and useful Improvements in Priming Cups, of which the following is a specification.

My invention relates in general to improvements in valves adapted to be used for priming and draining.

It consists in the elements and features of construction shown and described, as indicated in the claims.

The primary object of my invention is to provide a valve that can be used for either priming or draining and which is simple, reliable and economical to manufacture.

A further object of my invention is to provide a valve that has a threaded stem so that it may be pulled toits seat.

A still further object of my invention is to provide a valve that is really self-cleaning, that is that there is no small opening or passage but What is cleaned when the valve is turned.

My invention will be more fully disclosed hereinafter with reference to the accompanying drawing, in which the same is illustrated as embodied in a convenient and practical form and in which;

Fig. 1 is an elevational view partly in section; Fig. 2 is a bottom end view; Fig. 3 is an elevation partly in section of the valve portion itself, showing an optional form of handle; Fig. 4 is an elevation of an optional form of valve portion; Fig. 5 is a partly sectional elevation of a modification of my invention, showing its adaptation as a drain valve for a receptacle.

The same reference characters are used to designate the same parts in the several figures of the drawing.

A body 1 has a tapped opening --2 running through it. A rod 3 has a tapered portion 4 which forms the valve and closes opening 2, having a threaded extension 5 engaging threads in opening 2 to draw it to its seat 6-. The seat 6 is formed by slightly enlarging opening 2, enough to take out a few threads so as to leave a round hole and left with a sharp corner so that the valve --4-- may form its own seat.

The threaded extension 5 is shown the cross-bar 12.

its 'being made in one operation by a,

straddle mill. In Fig. 4 a slot 13 is shown as an optional form of opening to allow the liquid to pass when the valve is open. Fig. lshows the valve rod extended and bent toform a handle 9, while Figs. 3 and 4 show an optional form of handle in The threaded portion 5 extends through and beyond opening 2 to .m-ake self-cleaning possible. In connection with self-cleaning feature, it will be noticed there is but one hole through which the liquid flows through so that it is absolutely self-cleaning. There are many so called selfnleaning valves but they invariably have one or more holes that are not self-cleaning. I

WVhen desired to be used as a separate unit the body --1 is provided with a male thread 10 adapted to be attached to standard fittings.

hen it is desired to use the valve as a priming valve, the body 1 is provided with a cup-shaped portion 11 to facilitate pouring of liquid to the valve.

Fig. 5 is a modification of my invention, with the hande formed from the opposite end of the valve rod, that is the handle 18 is made by extending the threaded stem 17, instead of extending the valve end 16 This modification is shown as a drain valve, the body portion -15 is shown soldered to the bottom of a receptacle Having described my invention, what I claim 1s:

1. A priming valve comprising a body having a cup portion, a valve seat at the bottom of said cup portion, a threaded opening below said valve sea-t, a valve stem for said body having a manual control handle at one end, a threaded portion at the other end, avalve portion formed on said stem intermedi ate said manual control handle and said threaded portion, said threaded portion having a longitudinal portion cut away to al low the passages of liquid and loosen dirt when said valve stem is turned. i

2. A priming valve comprising a body having a cup portion at one end, a threaded opening intermediate said cup portion and the other end of said body, a valve seat in- 2 a g r 1,529,772
